Log Message:
re2c: update to 2.0.3.

2.0.3 (2020-08-22)
~~~~~~~~~~~~~~~~~~

- Fix issues when building re2c as a CMake subproject
  (`#302 <https://github.com/skvadrik/re2c/pull/302>`_:

- Final corrections in the SIMPA article "RE2C: A lexer generator based on
  lookahead-TDFA", https://doi.org/10.1016/j.simpa.2020.100027

2.0.2 (2020-08-08)
~~~~~~~~~~~~~~~~~~

- Enable re2go building by default.

- Package CMake files into release tarball.

2.0.1 (2020-07-29)
~~~~~~~~~~~~~~~~~~

- Updated version for CMake build system (forgotten in release 2.0).

- Added a short article about re2c for the Software Impacts journal.

2.0 (2020-07-20)
~~~~~~~~~~~~~~~~

- Added new code generation backend for Go and a new ``re2go`` program
  (`#272 <https://github.com/skvadrik/re2c/issues/272>`_: Go support).
  Added option ``--lang <c | go>``.

- Added CMake build system as an alternative to Autotools
  (`#275 <https://github.com/skvadrik/re2c/pull/275>`_:
  Add a CMake build system (thanks to ligfx),
  `#244 <https://github.com/skvadrik/re2c/issues/244>`_: Switching to CMake).

- Changes in generic API:

  + Removed primitives ``YYSTAGPD`` and ``YYMTAGPD``.
  + Added primitives ``YYSHIFT``, ``YYSHIFTSTAG``, ``YYSHIFTMTAG``
    that allow to express fixed tags in terms of generic API.
  + Added configurations ``re2c:api:style`` and ``re2c:api:sigil``.
  + Added named placeholders in interpolated configuration strings.

- Changes in reuse mode (``-r, --reuse`` option):

  + Do not reset API-related configurations in each `use:re2c` block
    (`#291 <https://github.com/skvadrik/re2c/issues/291>`_:
    Defines in rules block are not propagated to use blocks).
  + Use block-local options instead of last block options.
  + Do not accumulate options from rules/reuse blocks in whole-program options.
  + Generate non-overlapping YYFILL labels for reuse blocks.
  + Generate start label for each reuse block in storable state mode.

- Changes in start-conditions mode (``-c, --start-conditions`` option):

  + Allow to use normal (non-conditional) blocks in `-c` mode
    (`#263 <https://github.com/skvadrik/re2c/issues/263>`_:
    allow mixing conditional and non-conditional blocks with -c,
    `#296 <https://github.com/skvadrik/re2c/issues/296>`_:
    Conditions required for all lexers when using '-c' option).
  + Generate condition switch in every re2c block
    (`#295 <https://github.com/skvadrik/re2c/issues/295>`_:
    Condition switch generated for only one lexer per file).

- Changes in the generated labels:

  + Use ``yyeof`` label prefix instead of ``yyeofrule``.
  + Use ``yyfill`` label prefix instead of ``yyFillLabel``.
  + Decouple start label and initial label (affects label numbering).

- Removed undocumented configuration ``re2c:flags:o``, ``re2c:flags:output``.

- Changes in ``re2c:flags:t``, ``re2c:flags:type-header`` configuration:
  filename is now relative to the output file directory.

- Added option ``--case-ranges`` and configuration ``re2c:flags:case-ranges``.

- Extended fixed tags optimization for the case of fixed-counter repetition.

- Fixed bugs related to EOF rule:

  + `#276 <https://github.com/skvadrik/re2c/issues/276>`_:
    Example 01_fill.re in docs is broken
  + `#280 <https://github.com/skvadrik/re2c/issues/280>`_:
    EOF rules with multiple blocks
  + `#284 <https://github.com/skvadrik/re2c/issues/284>`_:
    mismatched YYBACKUP and YYRESTORE
    (Add missing fallback states with EOF rule)

- Fixed miscellaneous bugs:

  + `#286 <https://github.com/skvadrik/re2c/issues/286>`_:
    Incorrect submatch values with fixed-length trailing context.
  + `#297 <https://github.com/skvadrik/re2c/issues/297>`_:
    configure error on ubuntu 18.04 / cmake 3.10

- Changed bootstrap process (require explicit configuration flags and a path to
  re2c executable to regenerate the lexers).

- Added internal options ``--posix-prectable <naive | complex>``.

- Added debug option ``--dump-dfa-tree``.

- Major revision of the paper "Efficient POSIX submatch extraction on NFA".

----
1.3x

  + ``YYMTAGPD``

- Added configurations:

  + ``re2c:sentinel = 0;``
  + ``re2c:define:YYSTAGPD = "YYSTAGPD";``
